Phono Inputs
Phono Turntables must be fitted with a magnetic cartridge with nominal output level
between -55dBV and -25dBV (1.77 to 56mVrms). The WARM2 PHONO inputs (26
and 31) have high headroom (margin before saturation) and they can handle higher
output cartridges than what is usual. These inputs are supplied with a nominal input
sensitivity of -40dBV (10mVrms). Act on TRIM control in order to adjust the input
sensitivity depending by the cartridges in use.
Line Inputs
The sensitivity of the inputs marked as LINE (27-27-30) is 0dBV (1Vrms). You can
connect sound sources such as CD or digital players, as well as keyboards and other
instruments.
Microphone Input
The MIC input (29) is ready for a nominal input level of -50dBV (3.16 mVrms). The
connection of balanced signals is as follows:
Hot or direct signal > Tip
Cold or inverted signal > Ring
Ground > Sleeve
Low impedance (200 to 600) monophonic microphones must be used. For non
balanced microphones we recommend monophonic jack plugs although stereo ones
are also suitable if the ring is short-circuited to the sleeve. The WARM2 includes 18V
Phantom power for condenser microphones. An internal jumper allows disabling the
phantom power. The WARM2 MICRO input is delivered with enabled phantom power
by default (see the configuration diagram).
